Colorado a corporation of Application lOctober 28, 1929,4 Serial No. 403,045 claims. (o1. 19a- 220) This invention relates to reciprocating 'con-v veyers of the type in which a trough vor other conduit is reciprocated with strokes of different lengths to effect an advancing movement of ma- 5v terial from a point of supply at an end of the trough or conduit to a point of discharge' at the opposite end of the same. 4,

The rearward movement of the conveyer to the source of supply is accelerated with lrelation to its forward movementytoward the point oi delivery so that the material fed onto the conveyer will be graduallyV advanced bythe forward movement of the conveyer and by its own momentum and inertia during the more rapid rearward movement of thesame.

It is an object of the present invention to provide ak conveyer of the above described character, transportably mounted upon a wheeled truck and thereby particularly adapted for use in mines equipped with railways for the transportation of the excavated product'.

Another object residesv in the provision of a simple and highly etlicient mechanismA for the operation of the reciprocating element of the machine and still other objects reside inthe provision of certain adjustments adapting the machine for use under varying conditions'and in details of construction and novel and-useful combinations and arrangements of parts as will be fully explained in the course of the following description.

- In the accompanying drawings in the several views of which like partsare similarly designated,

Figure l represents a partially broken plan View of the improved conveyer.

Figure 6, an enlarged cross section taken on the line 6 6, Figure 4.

Referring further to the drawings, the conveyer comprises a truck 5 the wheels' 6 of which are flanged to move on a railway track 7.

The body of the truck is provided with boxes for the axles of the wheels and with suitable bearings for the support of the gearing by which a `conveyer trough 8 supported for'reciprocation on the truck, is operated. 'j

An electric motor 9 mounted at' an end of the truck body carries a groovedvpulley 10, which transmitsthe movement oiits rotor, to` a similar pulley 12 at theend of a jack shaft 13, through the medium of a plurality of belts 14.

A crankshaft 15 is provided with gear wheels I 16 that mesh Vwith pinions 17 on an intermediate shaftA 18, and gear wheels 19 on the last mentioned shaft mesh with pinions 20 at the ends of the before mentioned jack shaft. 4 Theshaft 18 provides a support for a duplex rocker arm 21 which by means of apitman'22 is operatively connectedr with the crank 23 of the crank shaft 15.. Y

Two parallel rods 24 connect the rocker arm 21 with the conveyer trough.

The arrangementrof thecrank and the rocker arm is such that by rotationof the crank shaft in the 'direction of the arrowY in Figure 4, a dilerential reciprocating movement yis imparted to the trough', the `forward movement in `the directionof the point of `disclflarge being slow and the return movement in the direction of the arrow A invFigure 4, being comparatively lapid.- Y. .The rockerarm has a plurality of apertures 25 for the attachment of the connecting rods so that the ratio of the differential movements of the conveyer trough may be varied within determinate limits. The conveyer trough consists of aV master section 26 directly mounted on the truck and a v plurality of extension sections 27 which are conneoted to follow the' reciprocating movement of the master section, imparted thereto by the motorthrough the intermediary vof thehereinabove described 'transmission mechanism.

LAll of the sections are nat-bottomed with daring sides and outwardly projecting flanges at the upper edges of the sides.

The entire trough slams upwardly from 'its feed end for the purpose of discharging the material at an elevated point of delivery above a pit carv or other suitable receptaclaand the master section is withthis end in View, slantingly supported on the wheeled truck.

Fastened to the body of the truck by two pairs of plates 44 are parallel slanting side rails 28 on which are mounted a `plurality of rollers 29 that are 'engaged by the Ianges 30 of the master section of theA trough.

A stiiening plate'm31 fastened beneath the bottom of the master section engages the' rollers opposite to the flanges and thereby holds the section against upward displacement.

Both the flanges and those provided by the plate 31 have strips 32 of Wear-resisting metal that engage the rollers.

Cross bars 33 fastened to the side rails of the truck body by means of their upwardly bent end portions 33o oari'y rollers Se that hold. the ter section against lateral displacement by engagement with parallel angle bars 35 secured to the bottom of the section at opposite sides of the rollers.

The extension sections 27 at oppeeite ends-ef the master section are secured to each other and to the master section by belts or other suitable means.

The sections overlap one another at their ends and they are provided with outwardly eroieoting ears 36 for the application of the bolts which fasten them together.

The vSeotion at the .extreme .enel oi the trough at which the materiallto be conveyed ie fed into the treuen. has a dat forwardly nreieetine Shovel el .that may enter into or beneath a nilo or" the material by rearward movement .of the trough, for the purpose. .of Selle-.feeding- The Shovel may be provided with a plurality of lingers 33 to facilitate its entrance into the material.

It will be understood that the length of the conveyor may be varied according to different conditions by adding or removing the sections at opposite ends of the master section, but a more limited adjustment may be obtained by providing two adjoining sections, preferably at the feed end of the trough, with lapping ,flanges whieh have a .Series oi reeisterinehole'o te .for the reception of one o r more belts by which the Sections are .fastened togethery all as. Shown in Figures 1 and 2 of the drawings.

It will be apparent that by these .meant the .troush may he lenethened to a limited extent, whieh iS of particular importance when it le desired to advanoe, the .Shovel end of the trough, inte the material at inoreaeine distantes from the truole.

The extensions at the feed end of the trough .lie Supported on the ground, as. .Sli-own but at the unser or delivery .end 'of the truck it .is desirable to provide .soeeial means to relieve the master .section oi the weight of the exten: sion sections. y

The volteoy as heet Shown in .Figure 5, may be made of vhinged parts to facilitate their manipulation and'application. They are shaped in conformity with the trough-like sections be,- neath which they are olaoed and they have outwardly eroieotine slotted. ears 43 to admit a linie of the' ehairue i It will be seen that the swinging support thus provided does not interfere with the reciprooatins motion oi the oonveyer and .permite oi eXtendihe the eohveyer to any .desired length in the operation of the machine, the Wheeled truck is moved .alone the railway traok .to a ooduring each subsequent quick return motion oi the troug', the material either continues its forward movement by its momentum or it remains inr'place by its inertia While the trough moves beneath the same.

In this manner the material is gradually advaned until at the upper end of the trough it falls into a pit car or other receptacle placed beneath raidl end The maeliine ie eartioularly adapted for use .in eoal .to earry the mined Coal to the oit ears ey'nowen-driveri. mechanical means- The oanaeity oi the maehine may he inoreaaed by manually supplying material to the reeierof eating trough at the'ieed end of the same in addition to the material ted onto the trough. by the Shovel- Conveyers oi-Y the described type which are reoinrooeted at different veiooitiee in opposite directions fer the purpose oi gradually advancine material .from a. noint of Supply to a distant point of dieohareeI are known in the art, and the present invention consists mainly in the particular means for operating and constructing the eonveyer as enorm,` and described. the means of adjustment and the method of adapting the inaehine for the ear-tisular purpose of minine eoal and other nrooluete, Set .forth in the hereunto appended claims.

Distinctive features of the invention are that the eonveyer may be readily transported from .one eert .of .a to another, that the 4temion eeetions. are readily removed and replaced befere and after the truck has been moved to a new ooint of operation, that the drivine-meohahiem .aets on but .one trough .See-l tionwhieh aotuatee the entire eonveyery that the drive unit is the only Part of the maehine requiring lubrication, and that the ratio of the differential movement .of the Conveyor may be varied according to the nature of the material to be conveyed.
